# APKBUILD based on linux-vanilla aport. Changes:
# - disabled module installation
# - add !check !tracedeps
# - package: just install zimage-dtb and kernel.release
#
# Kernel config based on: arch/arm/configs/dory_defconfig
# Changes:
# - apply patches to compile with gcc6
# - enable devtmpfs (needed for udev -> touch support in weston)
# - enabled CONFIG_VT (needed for weston to work)
# - disable ANDROID_PARANOID_NETWORK (removes network restrictions)
